Photochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion
In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

متن کاملThiocyanate determination by ion pair chromatography
Department of Analytical and Environmental Chemistry, Vilnius University, Naugarduko 24, LT-03225 Vilnius, Lithuania A simple and rapid ion pair chromatographic method has been developed for the determination of thiocyanate. Separation was carried out on a 25 cm × 4.6 mm Ascentis C18 column (5 μm particle size) with a mobile phase containing 2 mmol/l tetrabutylammonium (TBA)-phosphate (pH 6.5) ...
متن کاملSpectrophotometric Determination of Copper Piperazine Dithiocarbamate
Spectrophotometric method for determination of cu(II) in the trace quantities was developed by using piperazine dithiocarbamate as ligand in ammonium chloride-ammonium hydroxide medium at pH -9.5. The procedure developed was applied for the estimation of cu(II) in microgram quantities in the water samples and the method developed was found to be simple and sensitive. Spectrophotometry is one of...
متن کاملExtractive Spectrophotometric Determination of some Drugs Through Ion-Pair Complex Formation with Thiocyanate wnd Cobalt (II) or Molybdenum (V)
Two rapid, simple and sensitive extractive specrophotometric methods has been developed for the assay of Hyoscine butyle bromide (HBB), losartan potassium (LSR) and Sertaline HCl (SER) in bulk and in their pharmaceutical formulations. The proposed methods depend upon the reaction of cobalt(II)–thiocyanate (method A) and molybdenum(V)–thiocyanate ions (method B) with the cited drugs to form stab...
